This is a very useful patchbox that is perfect if you have a pedalboard that you like to use with different amps that are with or without a FX loop.

Version 2 of the Shifter Switch Patchbox has the benefit of no switch being needed, you just change the sockets that are used for each amp setup, plus without the switch we can add a TRS footswitch gang for if it is ever needed.

The patchbox is wired so the amp's FX loop's ground is isolated to avoid a ground loop.

By default, the pedal comes with black nuts, in the options above you can select for them to be coloured if you would prefer them.
